Plan drawing of a rowhouse on a 30.4 by 30.6 metre lot, 2 storeys, 4 dwellings, 36 rooms. Dwelling U0 (2BR) has 9 rooms totalling 229 square metres. Dwelling U1 (2BR) has 9 rooms totalling 228 square metres. Dwelling U2 (2BR) has 9 rooms totalling 304 square metres. Dwelling U3 (2BR) has 9 rooms totalling 235 square metres. Building footprint 498 square metres; open space 433 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.88, daylight 0.53, privacy 0.86, circulation 0.59, carbon 0.95, cost 0.90.
